Description
Technical field
The invention belongs to oiliness sewage treatment technical field, and in particular to the processing method of a kind of oil-containing and oil wastewater and
It efficiently separates system.
Background technology
With the development of the social economy, the waste water pollution problem that process of industrialization is brought becomes increasingly conspicuous, environmental pollution is more next
More paid attention to by the people, and oil-containing and the waste water of grease type are common in numerous waste water, easily bring the work of environmental pollution
Industry and sanitary wastewater, harm is serious, and its processing at home and abroad attracts great attention.At present in petrochemical industry, vehicle cleaning, machine
Oil-containing and the waste water of grease type can be produced during tool processing, food processing etc..Oil pollutant once enters water body at once
Oil film is diffuseed to form in the water surface, prevents water body reoxygenation from air.Oils migration circle is wide, degradation speed is slow, finally influences people
Class health.It is different according to existence form of the source of oily waste water with oils in water, it can be divided into：Oil slick, dispersed oil, oil emulsion
With the major class of dissolved oil four.These oil components are complicated, containing a large amount of mineral oil or vegetable oil, emulsifying agent and other organic principles,
Property is stable, it is big to remove difficulty.So how efficiently to carry out water-oil separating to reach discharge standard is still a problem.Cut-off
Up to the present, the method for more commonly used processing oil-containing and the waste water of grease type mainly have gravitational separation process, centrifugal separation,
Bubble-floating Method, ultra-filtration filters method and absorption method etc..This several facture has the advantage and disadvantage of oneself.Gravitational separation process and centrifugation
Method can only be in separation water oil slick and the larger dispersed oil of a small amount of particle diameter, originally do not removed for the oil base of scattered, emulsification, dissolving
Effect.Therefore usually as the pretreatment unit of oily waste water.
By being passed through air and making to produce microbubble (also needing to add flotation agent or coagulant sometimes) in water in oil-polluted water,
Suspended particulate in floating carburetion, dispersed oil or the water that particle diameter is 0.25~25 μm in sewage is set to be attached on bubble, with bubble
The technology for climbing up on top of the water and being reclaimed.Bubble is because the buoyancy of itself takes oil droplet out of the water surface, to realize separation of solid and liquid process.
In actual applications, because waste water quality is different, the factor such as treatment effect and capital construction, operating cost, selected gas are considered
Floating technique is also different.It is different according to the method for producing bubble, air-flotation process technology be divided into air-dissolving air-float, vane type air supporting and
3 kinds of injection type gas floating.More commonly used dissolved air flotation has vacuum dissolved air flotation and method of pressed dissolved-air release, and the former is by various
At present using seldom, the latter is commonly used Bubble-floating Method for factor limitation.Bubble-floating Method is general and coagulation technology is combined, and can go
Most of dispersed oil in water removal, also there is certain clearance to the oil for emulsifying and dissolving, therefore be to use most oily waste waters
Processing method.But there are several big shortcomings in existing traditional Bubble-floating Method processing oily waste water：Oil slick is difficult, and flotation time stops length；
Sludge is easier to be deposited on flotation tank bottom, and release easily blocks；When treating capacity is big, airfloat equipment floor space is big, throws
Provide costly；Equipment globality is imperfect, cumbersome for installation；To the oily waste water based on oil emulsion and dissolved oil, traditional air supporting
Removal effect it is undesirable.
Ceramic membrane oil removal process is mainly used in condensed emulsified mineral oil in recent years.Although hyperfiltration technique under certain condition may be used
To efficiently separate profit, but caused fouling membrane can cause membrane flux deep fades in concentration process, and transmembrane pressure is substantially increased,
Membrane lifetime shortens soon, UF membrane efficiency degradation, causes energy consumption to increase.Most of milipore filter is put into after half a year is run
The frequent clean phase, a large amount of cleaning agents are not only consumed, and produce the secondary pollution problem of oil-containing cleaning fluid.Few milipore filters
Service life can be more than 2 years.Because the investment of film is generally larger, the initial investment of ultrafiltration oil removing system and operating cost are all
It is very high.Once in system due to pretreatment be not good at, concentrate precipitation etc. reason generation oil slick, milipore filter can be brought irreversible
Destroy, so as to cause the failure of whole system.
There is a method in which it is：Filtering and absorption method, this method is mainly with special filtrate (walnut shell, oil suction plastics)
Etc. adsorbing oil micro in water, but this method is suitable only for the situation that oil content is very low in waste water, otherwise can cause to filter
Expect saturation quickly.And the mechanical damage that can cause filtrate is frequently cleaned and regenerates, and due to being difficult to thorough backwash filtrate
Gradually it can fail, it is necessary to often be supplemented, operating cost is also higher.
On extensive use of the efficient flotation separation isolation technics in the wastewater treatment of oil-containing and grease, recent many water process
Manufacturer all proposes the viewpoint for being combined traditional air supporting and cyclone separation process, is achieved in the waste water of oil-containing and grease
Some achievements in research.
From above-mentioned, current existing treatment technology is difficult to obtain excellent processing to the waste water of oil-containing and grease to imitate
Fruit, particularly when oil-containing and the waste water of grease, when the component of this kind of waste water is more complicated, intractability also can accordingly increasingly
Greatly.
The content of the invention
For insufficient existing for current prior art, it is a primary object of the present invention to provide a kind of oil-containing and oil wastewater
Processing method；
Another main purpose of the present invention is to provide apparatus for the method efficient flotation separation piece-rate system, utilized
The efficient flotation separation separation equipment of research and development, pressure-air dissolving can be completed, agent molecule stretching puies forward effect, coagulation-flocculation stirring (pollution
Thing trap), flco formed, bubble nucleus generation all steps.
The goal of the invention of the present invention is realized by following technical step.
A kind of oil-containing and Oil Wastewater Treatment Method, processing step are mainly as follows：
1), first by medicament powder in advance through automated dispensing medicine system be accurately configured to certain density solution (or
The medicament that liquid has dissolved is diluted to the concentration of needs)；
2), water inlet is first into mixed pond soon, and coagulant is got in mixed pond soon by measuring pump, the coagulation in fast mixed pond
Agent mixes with raw water.Because mixer is that frequency conversion is set, so mixing pond fast, sufficiently long streamline is formed, is increased and medicine
The chance of agent collision, and because agitator frequency conversion is set, so that while medicament is sufficiently mixed with water, gravity flow enters next
In the first paragraph flocculation basin of level.Flocculation basin is flocculated using the two-part of standard at present, first paragraph mixing, second segment flocculation.It is conventional
Mixing speed gradient G value be 30-70S-1.Preferred relatively low oar blade type impeller prevents frangible floccule to be sheared.It is conventional
It is 5 to 20 minutes to design flocculation time, and the specific flocculation time of target water quality can be determined for compliance with by pilot scale.Temperature is to air supporting
The influence of technique is less than traditional precipitation, and this is due to that microbubble quantity in saturator at a lower temperature can be
Increase, so as to improve capture rate.The usual scope of hydraulic loading rate is 4-8gpm/ft2.Therefore, efficient flotation separation piece-rate system institute
The floor space needed is fewer than precipitating；
3) after, a small amount of floccule is formed, raw water mixes in efficient flotation separation piece-rate system reaction zone with dissolved air water, 80-90psi
Compressed air be dissolved in water and reach saturation, dissolved air water typically uses pneumatically supported water outlet, typically 8-10% water yield
Reached by reflux pump in dissolving, reflux pump is controlled by VFD, for maintaining the balance of dissolving, the molten gas of built-in filler
Tank mixes the water after clarification and compressed air, and dissolved air water is released in the distribution header of air flotation cell lattice width, and distribution is total
Pipe has a series of specially designed holes or nozzle.When pressure (hydraulic) water leaves nozzle, the decline of pressure produces millions of microbubbles
Group, size are about 20-100 micron diameters, and the permanent liquid level instruction in saturator is transferred to circulating pump VFD, so as to change pumping
Speed increases or decreases capacity of returns, maintains the operating water level in dissolving.In order to ensure pressure stability in dissolving, will have solid
Fixed current are flowed out by orifice plate.Horizontal plane in dissolving changes the consumption according to the void fraction of raw water.These are as ox
The microbubble of the same outward appearance of milk such as same spray blanket is discharged into contact area, and minimum spherical bubbles are according to stoke after conversion
The speed of this equation is risen to below laminar flow, and bubble rises through the water after flocculation, when floccule rises in air flotation cell lattice table
Face captures them when forming one layer of scum silica frost, and by rising microbubble from following support, the water outlet after clarification passes through this layer of scum silica frost
Bottom even distribution discharge of a series of side comb of bottom of pond along air flotation cell lattice.
4) scum silica frost formed at the top of efficient flotation separation separative element lattice, is periodically removed using mechanical Slag Scraping Device or hydraulic way
Layer, compared with the 1-2% solid contents that conventional depositing reservoir is formed, using mechanical Slag Scraping Device solids content generally 3-5%'s
In the range of.Leopold air-flotation systems can reach higher solid contents, so as to greatly reduce sludge dewatering or transport
Scum silica frost quantity (volume), therefore significantly reduce the cost of scum silica frost processing.
The processing efficient flotation separation piece-rate system of the waste water of oil-containing and grease, including automatic medicament feeding system, reflux pump, molten gas
Tank, release device, reaction tank, complicated groove, discharge bay, the medicament realize accurate dosing by automated dispensing medicine system, high
Pressure reflux pump squeezes into water in dissolving, and medicament and compressed air also enter Multi-stage spiral speed difference three-phase blender, empty in compression
After gas pours dissolving, gas is incorporated in water, after forming dissolved air water, by release, by dissolved air water release in reaction tank with
Raw water mixing after dosing, it is allowed to enter in reaction tank after fully contacting with pollutant, is constantly reduced with pressure, it is molten in flco
Gas slow release is grown up, and the moisture in flco is extruded, and gas and solid flco form Porous hollow form, and moisture content significantly drops
Low while itself proportion is more and more lighter, can not voluntarily be floated by external force, enters separate tank after ultimately forming scum silica frost, by dividing
Scum silica frost is struck off from the Slag Scraping Device above pond, follow-up dewater treatment is made in the slag bucket discharge that the scum silica frost struck off is connected below, separates
Water enter discharge bay through water outlet weir plate, then discharged by outlet pipe.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, high treating effect superior performance, stable water outlet are reliable；Few reagent consumption amount；
2nd, the quantity of slag is few, only 1/4 or so of traditional handicraft；
3rd, it is easy for installation, it is simple to operate, it is easy to grasp；
4th, removal efficiency is high, ranges up to more than 99%；
5th, small volume, takes up an area and saves, and construction investment expense is low；
6th, control is easy, no consumable accessory, no blocking, and maintenance cost is low；
7th, standardized product, nonstandard customization；
8th, it is small and uniform to produce microbubble, such as milk.
Compared with prior art, core of the invention is " air dissolving system and release system ", and " bubble derived from phase
Nucleus growth technology ", the former can effectively control the enough pressure that gas is dissolved in required for water, guarantee dissolved air water；The latter ensures
Gas fills whole flco under dissolved state after release, and countless micro bubbles are given birth to inside flco with periphery generation nucleus
Long, once pressure reduces, bubble can expand rapidly inside flco, and effectively be attached to flco periphery.And mixed in traditional
In solidifying air supporting, coagulant is with flocculant because invalid flco bridges, and flco moisture content is high, and reagent consumption amount is big, and bubble
It is larger, bubble molten gas rupture during rising, cause flco and particulate matter to be deposited to bottom of pond, cause the process of whole flotation
Failure, and its insufficient stirring causes many particulate matters to be captured by medicament, while the shakiness of floc particle and bubble
Fixed contact causes desorption phenomenon often occurs, and water outlet is difficult to control.Therefore efficient flotation separation piece-rate system of the present invention represents one kind
Advanced dissolved air flotation technique, its every characteristic have all surmounted traditional air-dissolving air-float.
